Soon enough they were outside, and their five nude friends all turned to them right away. Everyone else watched in puzzlement as Applejack pulled Rarity all the way out into the backyard.

"Oh my gosh!" Fluttershy gasped in exasperation.

"Ooo!" Pinkie cooed in curiously.

"Applejack? Rarity? What's going on?" Sunset asked in bewilderment.

"Yeah, what's up with you two?" Rainbow repeated.

"Rarity here squeezed my hiney and now she's gonna have to pay the piper." Applejack stated as she set the cooler down.

"No!" Rarity exclaimed in a dramatic but non-serious tone. She gave the girls an assuring wink to let them know that it was ok.

"Uh…" Twilight muttered as Applejack sat down on top of the cooler beside Rarity.

"And bad girls…" She started to say, "...need a nice, long, public spanking."

Rarity's heart leapt at those words with excitement while Applejack patted her lap.

"Come here Rare, bend over my lap and stick out your big old butt," she ordered as she continued to tap her thighs.

Rarity swallowed in mock fear, bowing her head in shame as she approached the seated country girl. She obeyed and bent over her friend's legs, presenting her big ol' derriere to all of the rest of her blushing friends behind her.

Applejack grinned and gently rested her palm onto one of Rarity's round white globes, feeling the muscles beneath it clench instinctively, which made the extra fat on it ripple just a little. She could barely hear the fashionista let out a quiet whelp when she touched and groped her bum.

"So many naughty acts you pulled with this big fanny of yours." AJ stated, giving the twin marshmallow cheeks a small pat, which only excited her waiting friend.

Fluttershy yelped. "Ah~ I can't watch this!" she said as she tried to cover her eyes with her hands again, but like last time she can't help but peek.

"Oh please don't…" Twilight begged in dismay.

"She-she's bluffing! I know she is!" Rainbow said, afraid and hoping she was right.

"I don't think so…" Sunset shook her head, equally afraid.

"Ooh! This is gonna be good!" Pinkie beamed as she grabbed a box of popcorn from out of nowhere and started eating handfuls of it.

"Raise your butt up." Applejack told the purple haired girl as she rubbed her friend's tush.

Rarity compiled by raising her lower body via standing on her tippy toes and lowering her upper half, making her d-cup breasts jiggle a little. Pinkie quickly got behind Rarity and looked over the two white orbs that could be mistaken for hills.

"Wow Rarity! I know I've said this before but wow that's a big butt!" she remarked. "I mean… you're butt could eclipse the sun!"

Rainbow snickered at this while Rarity's cheeks became red once more, though more out of embarrassment then arousal.

"Pinkie!" Sunset scolded.

"Hey Applejack, try not to make her raise it any higher or we'll be back in the dark ages!" Rainbow quipped as she and Pinkie burst into hysterics. Twilight and Sunset silenced them by giving them both a quick spank.

"That's enough you two." Twilight told them.

"Yeah, you're taking all the fun out of this." Sunset added.

"Say one more remark and it'll be your big behinds turning red." Applejack warned them.

"We know, we're sorry." Rainbow and Pinkie both said, lowering their heads and rubbing their tushes.

"Ahem, excuse me? Could we hurry this along? If I stay like this for too long I fear a bee could come by and see it as a target…" Rarity spoke up, somewhat scared.

"That'd be quite a show." Rainbow whispered before a glare from the usually demure Fluttershy made her stop.

"You got it Rearity." Applejack teased as she raised one hand while the other held one of Rarity's arms behind her back. Everyone held their breath as they watched, especially Rarity. "And here… we… go!"

Applejack brought her hand down quickly.

Smack!

That was the sound that was heard upon Applejack smacking Rarity's surprisingly plump posterior, causing the twin cheeks to jiggle and quiver like jelly and the owner to yelp in surprise.

"Ooh!" she suddenly squealed in delight before giggling.

"Like that?" Applejack asked, smirking.

"Oh, most definitely! Come on! Spank me! Spank me harder!" Rarity encouraged, eagerly while looking back towards Applejack.

"I think will," Applejack declared as she swung back again and smacked her rump a second time, only harder than before, making her jolt forward an inch or two.

"Oh my!" Rarity gasped.

And so the surprisingly pleasurable spanking continued. With each smack it sent something of a shockwave across her rump causing the flesh on Rarity's cheeks to ripple and quake while she continued to moan and squeal in delight. Applejack soon got into a rhythm as she paddled Rarity's right cheek and then her left and then her sitting spots, causing her rear to gain a nice shade of red.

As Applejack continued to raise her hand and bring it down on Rarity's rump, their friends watch on with sympathy, arousement as well as amusement and fear while Rarity cried out happily each time she was spanked. Twilight and Sunset both had their jaws hanging open, their eyes wide in disbelief at what they were witnessing. Rainbow and Pinkie were grinning and even finding the show entertaining. Meanwhile, Fluttershy was still hiding her face while taking occasional peeks, her whole body trembled in nervousness and embarrassment.

"Aw yeah! You go AJ!" Rainbow cheered on, encouraging the two of them to continue putting on a show for the rest of them.

"Wow! That is one red tushie!" Pinkie exclaimed in surprise, seeing how bright red Rarity's big, plump, rump cheeks were turning.

"I, I can't believe this is really happening." Fluttershy said in a shaky voice, but no one heard her.

Sunset looked over at Sci-Twi, who still has her jaw hanging open. "I'm a little bit worried Rarity's screams will be heard by someone else." The fiery haired girl whispered.

"Oh right, I didn't think about that. Well, Rarity did say she had a relatively secluded backyard." Twilight replied, looking over at the former bully.

"GAH! H-how many has it been?" Rarity asked shakily, her entire bum had changed into a bright shade of red from the repeated trauma brought on by AJ's strong arm.

"Heh, haven't been keeping count." Applejack told her, before swinging her palm fast down onto her friend's plump fanny, creating another loud smack.

Rarity's stinging rump rippled and jiggled, while she panted from exhaustion as well as arousal.

"Ok, I think that's it for now." The farm girl declared.

"Oh thank goodness. I'm not sure how much more my poor little bum can take."

"Little?" Rainbow echoed with a sly smirk, while heading over to the cooler and opening it. "Huh? Where are the drinks?"

"Oops, sorry. I might've forgot about them. Sorry… One sec!" Applejack responded sheepishly, before hurriedly picking it up and darting inside.

A few moments later, she returned back with a cooler full of ice and cool sodas.

Without explanation, Rarity speedily walked over and began taking out all the sodas in the cooler which the others took one by one.

"Um, Rares?" AJ questioned, but the fashionista took out all of the drinks.

Once all the drinks were out, Rarity turned around and sat her red tush right into the cooler, sitting on top of all the ice.

"Ahhh." A wide smile broke out across the fashionista's face as she sighed. "Much better."

Pinkie giggled while cracking open a soda. "That must feel super good right now, especially after that long spanking you got."

"You have no idea…" Rarity muttered in pure bliss, she felt as though steam was rising out of the cooler after having her hot buns touch the ice.

"Well, I'm definitely not putting my drink back in there now." Rainbow stated.

Rarity simply sighed in satisfaction, shifting and moving her hips and butt over all the ice, feeling it tumble and slide around beneath her sore bottom. In her state, she swore she could even hear it sizzling.

"I bet all that ice will be melted soon!" Pinkie quipped with a giggle, while opening another soda.

"Really though, how will I cool my drink off with your gigantic butt in the cooler?" Rainbow asked, to which the fashionista merely giggled airily.

"Rainbow, darling, excuse me for the bluntness. Ahem, you can kiss my big, bare, derriere." Rarity stated, a smirk evident on her lips.

The jockette stared at her for a bit in surprise, blushing just a tiny bit. Never had she thought she would hear Rarity of all people, saying those words to her. The rest of her friends all shared a chuckle upon hearing that, even Fluttershy giggled along with them.

"Hehe, what's the matter Dash? You say that all the time, don't ya?" AJ smirked, nudging the athletic girl.

"Yeah… but…" Rainbow started to say.

"Not used to your own medicine, Dashie?" Rarity challenged as she stood up, her butt now wet and still stinging a bit, not that she cared. She placed her hands on her hips as she continued to speak. "Or are you jealous of the fact that your derriere doesn't have the bounciness that mine does?"

As she said this, Rarity turned, put her hands behind her head and presented her behind to everyone, intentionally swaying it from side to the side and letting the extra flesh on it bounce.

If Rainbow wasn't blushing before, she most certainly was now. Her eyes followed the fashionista's wobbling butt cheeks like a hypnotic watch, entranced at how much the extra fat jiggled and rippled like jello.

Rarity peeked behind her and took notice, smirking even more as she reached a hand back to give her left cheek a smack. "Well, darling? Are you going to purse those lips up, and plant them right here or what?"

Rainbow snorted and stepped forward. "I got a better idea! Let's jiggle it out!"

"Beg pardon?" Sunset Shimmer remarked.

"She means we should all shake our booties until we can shake 'em no more!" Pinkie explained as she started to mimic Rarity.

"Last one standing gets decide what else we should do." Rarity added.

"Alright, let's get this started!" Rainbow declared with a bold grin, getting into position with her rear end jutting outwards at the rest of them. She flashed her grin back at the rest of them as she shook her bare ass at them.

"Yay! Shake those booties!" Pinkie cheered, shaking her hips from side to side in short quick motions, which made her plump, pink posterior ripple and bounce like crazy.

Sunset and Twilight soon joined in with the other girls, sticking their own rumps out at each other, and playfully shaking them side to side and up and down. They even began getting into the rhythm with a butt bump, gyrating their rears back and letting them smack into each other.

Fluttershy was as red as a tomato and shaking like a leaf. She kind of wanted to have fun with the rest of her friends, but it also seemed to be so embarrassing, for her at least.

Eventually, the urge to shake her rear end got to her and she ended up joining the others.

"That's it Fluttershy! Let it jiggle!" Pinkie cheered.

Pretty soon, all seven of the girls were lined up together with their hands on their knees and their butts moving from left to right over and over. They even reached down to touch their toes and raise their bums even higher.

Each of their rear ends were raised up towards the sky, bouncing and jiggling in what seemed like unison. All of them were giggling, laughing and having a good time despite being in their birthday suits.

Rarity smiled and looked over at all of her friends standing beside her, who were all smiling and enjoying themselves too. She even reached her arms out and wrapped them around her two friends standing to her left and right, who then all followed along and did the same.

Pinkie looked down for a moment while still shaking it, finding that her soda was empty. "Aw man, that was my favorite kind."

"Oh, you mean the soda? I have plenty more in the fridge." Rarity informed her, smiling and giving her a hip bump, which she eagerly returned back.

"Yay! I'll go and grab one quickly." Pinkie chirped as she left

This led to Rainbow grinning playfully. "Oh, yeah? Not if I beat you to it!" She announced and dashed off across the backyard, sliding open the door and closing just mere seconds before Pinkie could get there.

"Aww, Rainbow! You better not drink all of my favorite kind!" Pinkie said, but still smiled, planting her face and arms against the glass door.

Rainbow snickered from the inside and decided to taunt her friend stuck outside.

"Of course, what other better way to taunt your friend, than with a pressed ham?" The jockette thought as she smirked and bent forward, slowly swaying her rump at Pinkie before pressing it against the glass door.

Pinkie's view was filled completely up by a big wall of blue. She peeled her face from the glass door and saw none other than Dash's big blue butt pressed directly on the glass door.

"Dashie, you better stop that and let me in!" Pinkie declared, while giggling at the sight of Rainbow mooning her with a pressed ham.

Rainbow, however, couldn't hear her, or at least pretended not too. She snickered again and smirked behind her at Pinkie.

While their friends continued their fun, the others continued to sway their booties together before Fluttershy started to pant and slowly dropped to the ground, her head on the grass and her ass in the air.

"I'm pooped…" she sighed.

"Guess Fluttershy's out." Sunset observed.

"And since Pinkie and Rainbow left… they're technically out too." Twilight pointed out. The aforementioned naked girls heard this, and both moaned in dismay.

"Well, guess it's just us four now." Rarity stated, looking over at AJ, Twilight, and Sunset.

---

Meanwhile, Rainbow was taking great enjoyment in taunting her friend from the inside. She smirked smugly and shifted the pressure of her butt cheeks on the glass door, from left to right while Pinkie watched with wide eyes and red cheeks.

"Oh… I should be angered by this but seeing Dashie's blue butt makes me wanna grab it and kiss it forever!" Pinkie exclaimed. In fact, she did just that, puckering up her lips and planting them right onto the glass door, right where Dash's pressed buttocks were.

The sight, no surprise, amused the athletic girl greatly, making her smirk and snicker more.

"I could get used to this." Rainbow admitted as she turned back toward the fridge and let her rump wiggled against the window more. Without bothering to look back, she smirked and began rubbing her blue butt cheeks up and down the glass door, as well as side to side and even in circles. Each time the pressed skin of her ass dragged along the glass, it created a long drawn out squeaky noise.

When she finally did look back, she was stunned when she saw that Pinkie was gone.

"Wha the? Huh, guess she got tired…" she started to say before she heard the fridge door opening and closing. She turned around and her eyes bugged out upon seeing Pinkie Pie inside the kitchen drinking a soda.

"Wait, what!?" Rainbow exclaimed, making Pinkie giggle innocently.

"What's the matter Dashie?" The party girl asked oblivious, taking another sip from her soda. "You look like you've seen a ghost."

"You were just outside a few seconds ago!" Rainbow said, looking back outside. "How did you…. Huh?" She grew even more confused when she looked back in the kitchen and found no one there. The jockette rubbed her temples in utter bafflement, before deciding to check outside once more. However, as she went to the backdoor, she was met with quite a surprising sight.

"What!?" Dash exclaimed, her cheeks turning just slightly pink, upon what she saw in front of her; Pinkie pressing her own tush against the glass door and moving it from side to side tauntingly and making it squeak.

The party girl peeked over her shoulder, smiling cheekily at a stunned Rainbow, giving her a playful wink as she continued to rub and press her doughy pink globes against the glass door. Rainbow's cheeks quickly shifted from pink to red with embarrassment and anger as she growls in frustration.

At the same time, their friends watched what was happening while still swaying their badonkadonks back and forth and keeping their arms around each other.

"Well, that's unexpected." Sunset Shimmer remarked.

"It is Pinkie Pie after all." Twilight reasoned.

"So true." Sunset nodded.

"Are uh… any of you tired yet…?" Fluttershy inquired from close by as she watched the perverted display her friends were giving.

"Oh, umm…." Twilight fumbled with her words, before awkwardly shrugging while still keeping her arms wrapped around her friends.

"We can stop anytime you like, girls." Rarity told the rest of them.

"I can keep going for a bit longer." Applejack stated.

---

Meanwhile, Rainbow was blushing bright red as she stared at Pinkie's large, jiggling butt cheeks pressed flat on the glass. Even though she was a little bit peeved at being mooned by the party girl, a part of Dash kept wanting to stare at the almost hypnotic wobbling pink buns.

Pinkie herself was humming a happy little tune, smiling widely while sneaking the occasional glance back at the awestruck athlete inside. She knew that she was putting on quite a show for the jockette.

"Two can play at that game!" RD declared as she quickly went over and put her own buns on the glass door and began to mimic Pinkie's movements.

The only thing keeping the two girls' bums separated was the glass door between them. As the two of them pressed and rubbed their tushes against the glass, they could each see who's rear flattened more against the surface. Although Rainbow has a really big butt, which was well known by her friends, given how much she loved pressing it up against windows, Pinkie's posterior proved to be larger.

The party girl's pink, doughy buns wobbled and rippled like jello with even just the slightest movement against the glass. Since she often partakes in a diet consisting of lots of sweets, it's no surprise she has one of the largest tushes out of all of her friends, and right now it certainly showed, as it was squashed flat right up on the glass.

"Heh, not bad Pinkie." Rainbow admitted.

"Yeah, Dashie! Move that tushie!" Pinkie cheered on.

---

Around the same time, Sunset Shimmer dropped to her knees and panted, out of breath.

"Whoo… I'm out…" she said just as Twilight dropped down as well.

"Me too…" The sciencey girl added.

"Guess it's just you and me." Applejack stated as she eyed Rarity. "Ready sugar buns?"

"Oh, I was born ready, miss buns of steel." Rarity shot back confidently as they split apart.

The fashionista placed her hands on her knees as she bent forward a little bit more, putting her sizable derriere on full display to the rest of her friends, making them all blush in the process.

"Oh yeah? Allow me to counter." Applejack declared as she swayed her butt back and forth, the firm flesh on her buttocks moved much slower than Rarity's but it was enough to entrance her friends.

Pinkie quickly noticed this, and her eyes lit up. "Ooh! A twerk off!" she exclaimed, excited before zooming over to it.

Rainbow also saw what she did and smiled. "Alright! Hey, wait for me!" she called out as she quickly followed.

Not wanting to be outdone by Applejack's latest move, Rarity responded back by moving her ass up and down. The others all watched her ass jiggle and bounce as she bopped it up and down, their heads moving up and down with it.

Applejack however put more into moving her hips from side to side, grabbing and spreading them before letting them clap together.

The next thing Rarity did was place her palms on her knees and swivel her hips back and forth. Applejack countered again by putting her hands on her knees and moving her rear around in circles. Rarity quickly spun around and began to pop her hips up and down, making her assets bounce.

The rest of the girls sweated hotly while watching the two of them trying to one up each other with different dance moves. Their eyes were locked onto the jiggling posteriors of each competitor, following it in a trancelike state.

"I can't take my eyes off of…." Twilight paused and blushed.

"Their rears? Don't worry, I think we all can't." Sunset stated, while still watching.

Rarity buckled her knees and reached both hands back to pat her plump fanny, sneaking a sly smirk at the country girl behind her as she did so.

"Oh yeah?" Applejack challenged. "Well let's see how you like this."

Applejack moonwalked over to Rarity, popping her hips out upon getting close enough to her. Rarity quickly lost her balance, and fell to the ground. Applejack promptly sat down and grinded her booty against Rarity's while keeping her pinned.

"Oh, you're so going to get it!" Rarity grumbled while AJ chuckled atop of her, smugly grinning as she rubbed her firm backside against the fashionista's bum.

"Heh, I guess that means I, whoa!" Applejack's eyes widened as she felt herself being pushed off of her pinned friend. Next thing she knew, she was laying on the grass, and Rarity was smirking down at her.

"Martial arts, dearie." The fashionista stated, before turning around and promptly sitting on the farm girl's back.

"Oof! Dang Rares, you're heavy." Applejack said, feeling the immense weight of Rarity's big butt resting on her, keeping her pinned in place this time.

"I will take remark as a compliment." Rarity stated. "Now… do you want me to get off?"

"Yes!" The farm girl expressed with some pain in her voice, she felt as though the immense weight of Rarity's tush was crushing her.

"Then say it." Rarity said in a sing-song voice.

"Fine… I give…" Applejack sighed, defeated.

"Indeed you do." Rarity declared as she got off of her and helped her up.

"Well Rarity, looks like you win." Rainbow stated. "Fitting since you're the one who started all this."

The others all voiced their agreements at the same time.

"Indeed. Indeed I am." Rarity nodded, proudly.
